I'm using a VNA (at8722es) to do my HF measurements. I retrieve the data of my measurement via an usb-gpib interface connecting my vna to the computer. At the moment I get the datapoints, put it in an array and send it to a labview plot.
But I would prefer to take a capture of the vna's screen and send it to my computer. Ive seen a tool doing this but can't find anx hints how to. Maybe something like setting the gpib port to the default printerport and doing a print ...
Well, it sounds like you just want to emulate a plotter? We went through this not too long ago - I found an application that does just that, called Plottergeist (lol). It works great. It is commercial, but you can get a demo to check it out. Just google it.
